The M312V Vampire Weaponlight by SureFire is the perfect addition to a nighttime shooting setup. It features 2 modes; "normal" light and infrared light. The "normal" mode produces a powerful beam of 250 lumens, while the IR mode gives off 100 milliwatts of infrared light, completely invisible to those without night vision devices. Twisting the self-locking bezel-ring switches between modes instantly, and can be done without even looking. The M312V can be mounted onto any platform using a MIL-STD 1913 Picatinny rail mount via an RM45 mount. This system will give the M312V an offset position to decrease the weapon's profile and reduce the chance of snagging.
